The metadata vocabulary is a very useful component of our Browser. It organizes hundreds or thousands of data tracks in a meaningful way, underlies the metadata color map, and allows creation of custom entries. Before this date, the metadata system hasn't been well designed -- repetitive components and duplicative code, cluttered user interface and rigid usability.
Now it has got a complete redesign! Highlights are following:
Above described components are related to Browser-provided metadata vocabulary. The lower component is related to custom metadata. Click button to launch the function:
Just fill up the blanks as instructed in the example:
Press button to make the new metadata term:
And check the checkbox following "my friends" to display the term in metadata color map:
The custom metadata terms can be saved in session function.
2. Annotating custom bigWig tracks
At control panel, go to "Tracks" > "Custom track", and click tab "bigWig" to show the custom bigWig track submission panel:
When submitting a custom bigwig track, you can make metadata annotation to it, and this step is optional. You can always add or edit metadata annotation at a later stage.
Click button , the metadata management panel appears:
Open up the vocabulary tree and find terms to annotate the custom track. Only leaf-level terms can be used by checking the checkboxes, the term will be displayed in a new table:
You can select an attribute from the custom term we created above to have it displayed in this table:
Notice the difference of how server-provided and custom terms are presented in the table. Click X to remove term from the table.
Click button to submit the track. Here we give it a dummy name "aa bb". Right click on the track in genome heatmap and option "Edit metadata" can be seen in the menu:
Select the option to open the metadata editing panel in floating toolbox, the existing metadata of this track will be shown here:
You can repeat the same procedures to add or remove metadata entries for this track. The metadata color map will update on the fly.
Now it has got a complete redesign! Highlights are following:
- New interface to a centralized metadata user interface, allowing you to browse and manage metadata at one place. Code duplication and forking has thus been eliminated.
- Editing metadata for custom bigwig tracks.
1. New metadata management system
At control panel of the Browser, click tab "Metadata" to find the metadata browser panel:
Shown are root level terms of metadata vocabulary of human database. Click on a term to navigate through the vocabulary:
Check a checkbox to have the term displayed as one column in metadata color map:
Above described components are related to Browser-provided metadata vocabulary. The lower component is related to custom metadata. Click button to launch the function:
Just fill up the blanks as instructed in the example:
Press button to make the new metadata term:
And check the checkbox following "my friends" to display the term in metadata color map:
